PEDOGRAPI-I AND METATARSAL-PAD LOCATOR.

Application filed July 22,

I foot impression is to betaken.

The present invention has for one of its ob jects to improve this device to the end that it may also be used for taking the impression of the arch of the foot for use as aguide in p the placing of a metatarsal pad in the shoe.

WVith the foregoing and other objects in view, the nature of which Wlll become apparent as the description proceeds, the in vention consists of the novel construction, combination and arrangement of parts hereinafter fully described andclaimed, and illustrated in the accompanying drawings, wherein:

Figure 1 is a top plan view of the pedograph embodying my invention, the device being shown adapted for the'purpose of taking foot impressions,

Figure 2 is a view in front elevation of the device, a

Figure 3 is a View similar'to Figure 1 showing the device adapted for the purpose of taking the impression ofthe arch of the 'foot, l 1 e Figure 4 is a transverse sectional view taken on the vertical plane indicated byt-he line l4- of Figure 1,' i

to in the following description, and desigratcd in the severalviews of the accompanying drawings, by similar reference characters. 1 The pedo-graph comprises, as shown in, the

drawings, ashallow receptacle ,1; -The upper side of the front portionl ot the receptacle is fully open, and the rear portion of the receptacle is formed to provide a housing 1 A plate 2' upon which is placed the 192s jSerialNo. 124,229.

sheet of paper to receive the foot impression, 15 arranged wit-hmthe receptacle portlon 1?.

which is wound an ink carrying member 3, is journaled within the housing 1 The ink carrying member 3 passes through an open ing a in the front side of the housing'l and located within the opening and below the ink carrying member is an inkingdevice 5, of

well known construction, for applyingink to said member as it is unwound from the; spring pressedroller to which it is secured. A bail 6 which is connected to the front edge of the ink carrying member 3 and pivotally secured A spring pressed. roller, not shown, upon as at 7 to the ends of the receptacle portion 1, provides means for limiting the extent to which said member may be wound on the spring pressed roller and for holding said member against the tensionof said roller over the plate 2 when the impression of a foot is being taken. e A pull 8 is secured to the front end of'the ink carrying member 3 to permit said member to be readily extended over, the plate 2 and to also permit the bail6 to be lifted whenit is desired to permitsaid memher to be rewound by and on the spring pressed roller. A heel plateor rest 9 is re- ,movably positioned in a slot 10. f

In accordance with the present invention, the plate 2 is made in two parts or sections 2 and 2 The'plate section 2 is permanently fixed within the receptacle portion 1 and the The heel plate 9 rests upon the bottom of the receptacle-portion 1, and it is removably supported inupright position thereon by the plate section 2, block 12 and adjacent end The outer.

end of the plate sect-ion 2 is provided with notched lug 13 which is adapted to be used for and-when adjusting" this plate section with respect to the plate section 2 The lug 13 projects beyond the adjacent end of the receptacle portion 1 and said end of said portionis provided with an opening 1 1- for the reception of the plate section 2?. The adjacent 'endsof thelplate sectionsfz and 2 have bevelled under sides and16, respectively. A spring plate 17 is secured within adjustment of the plate section 2 will depend solely upon the length of the foot of 1 which the impression ofthe arch is to be taken. 7 To enable the accurate adjustment of the plate section 2 the front upper edge of thereceptacle portion 1 is provided with a scale 18. After-the plate section 2' has been adjusted, the exposed portion of the spring plate17 is arched or bowed upwardly above the plate sections 2 and 2" by a cam 19. This part is located below the spring late 17 be- (ill ' plate 2" :is drawn bac-g until its edge 16, is in line with the number on tween the guides 12', and is Carrie by a shaft 20 which is slidably and rotatably. supported by theguides and to the outer end of which a lever21 is secured. A plate 22 is secured to the front side of the receptacle portion 1% and is provided with an a-rcuate series oi" openings A bolt 24 fixed to the handle 21 and provided with a knob 25, is adapted, as the shaft 20 is slidably as Well as rotatably supported, to be arranged in any of the openings 23 in the 7 late 22 to secure the cam 19 inadjusted pos tion against casual .movement. The cam 19 normally occupies an inactive position, in which position thereof it is out of contact wit 1 the spring plate l7, audit may be swung through any angle fromthis position through the medium of the knob 25, the extent of the adjustment of thecam 19 depending solely upon the arch or "how it is desired to impart to the s ring plate 17. The beveled ends 15 and 16 of the plate sections 2? and 2 permit the ready adjustment of the latter section. 1 J

To use device to measure the foot for shoe size or to diagnose the variousforlns offoot ailments, it is used with plate-2 'shoved in until it comes in contact with 2, which forms a flat base over which a sheet of aper 26 with a standard foot measuring sea e printjeclon the upper side is placed. Thereafter the ink carrying member 3i's adjusted or extended over the sheet of paper 26, The placing of the foot upontlie ink carrying member 3 will result in an impression of the foot being made on the paper overa flat surface.

0 use for locating the sitionin the shoe should be placed, away from plate 2* i where the metatarsal scale 18 to 'corres end with the Si e of shoe into which the pa is tobe built. The cam 19 is next adjusted 'to arch or bow the spring built. Theredft'erihc'link carrying me1n-' plate 1? ward between plates 2 and 2" to a height b" correspond With the height of the arch of the shoe into which the pad is to her 3 extended over the sheet 0 paper 26. I The foot is placed upon the ink carrying memher-,3 directly over the arched plate 17. Heel plate 9 is then removed from. its normal position and used as a guide to mark theposition of the back of the heel on the paper 26 The impression thus made on the paper will show the length of the foot and the posh tion of the arch therein, and from this data the point at which the arch should be located in theshoe may bereadil determined,

"To use the device for ma fling shoes toord'er for-either crippledor' norlnal feet, the size is first determined as herelnbefore explained; the late 2 is then drawn back awayfroni 2"- until its edge 16.is'in line with the numher on the scale '18 corresponding with. the sizedetermined, and the foot is then placed over s ring plate 17 The cam 19 is next aajaa a) raise sprin late 17 to come in, contact with the are of the foot firmly enough to give the dtlsired Shank sup.- port; The footis then removed and paper 26 is plaeed'over springplate 17. Also ink carrying member is brou lit forward to extend over paper 2'6. The bot isplaced upon the ink carrying member 3 and a mark made to determine the back of the heel will result in the impression of the, foot.- .Thus' it is possible to make the depressions and raises in the insoles of 'the shoes under construction iit the sole of either a crippledor a n'ormal oot.

It should be understood'that the drawings are Inerely illustrativeand do not pretend to give exact proportions. A F urthermole, the said drawings are illustrative of a preferred construction, it being my expectation that varim s changesand modifications may be 2 g from the spirit and 2 V I no made'without departjin scope of my invention.
